The genus Sommieria used to contain three species, all native to northwestern New Guinea. In 2002, however, botanist Charlie Heatubun joined the three into a single species, Sommieria leucophylla. It is a variable, smallish undergrowth palm native to wet lowland rainforests. It grows with an underground or shortly emergent, solitary trunk, about 3 cm (1 in.) in diameter. The crown holds numerous, usually entire, deeply bifid leaves that are dark green above and silvery white to golden below. It is closely related to Pelagodoxa, with which shares the same curious, warty, albeit much smaller fruits. In cultivation it is still very rare. It is slow growing and requires a protected spot in the tropical garden with ample moisture. Even though under botanical criteria, the reduction to a single species makes sense, horticulturally the three original species are somewhat distinct. Sommieria leucophylla in the original sense, as offered here, is found in Western New Guinea (formerly Irian Jaya). It differs by usually having two leaflets on either side of the leaf midrib, which are dark green above with a bluish cast. The leaf underside is a superb silvery white. It grows to about 2 m (6 ft.) tall.
